The invention discloses a charging plug, a charging socket and a charging system. The charging socket comprises a hole and a first clamping piece; the hole is formed in the end part of the charging socket, the hole is matched with a conductive terminal of the charging plug, a waist-shaped crown spring is arranged in the hole, and the waist-shaped crown spring is used for connecting the conductive terminal with a charging end of an energy storage assembly of a vehicle; the opening of the hole is provided with an extending section extending towards the center to form a clamping groove, and the clamping groove is used for fixing the kidney-shaped crown spring in the hole; and the first clamping piece is connected with the clamping groove in a clamped mode, the first clamping piece is used for being connected with a second clamping piece of a charging plug in a clamped mode, and after the first clamping piece and the second clamping piece are connected in a clamped mode, the first clamping piece and the second clamping piece can be pushed by first stress to move in the inner diameter of the kidney-shaped crown spring. The problem that a large-size terminal does not meet the requirement for high-voltage safety of preventing fingers from making contact with a high-voltage conductor is solved, the dustproof and anti-corrosion capacity of the terminal is enhanced, and the terminal is simple in design structure, low in cost and convenient to use.
Description
technical field [0001] The present application relates to the technical field of charging, and in particular to a charging socket, a charging plug and a charging system. Background technique [0002] After years of development, electric vehicles have basically matured. However, the charging speed of the vehicle is relatively slow and the charging time is long, which is not conducive to the use of users and affects the further development and promotion of electric vehicles. In order to increase the charging speed of electric vehicles, there is an urgent need to research and develop high-power charging. The charging interface is the connection interface between the vehicle and public charging equipment for charging. The overcurrent energy of the charging interface directly affects the high-power charging capability. [0003] Due to the safety requirements of "preventing finger contact with high-voltage conductors", the conductor terminals of the charging connection interface ...
